Setting Horizontal Line (NSBox) line width in Interface Builder

Question

I have an application that I am building am making use of Horizontal Line (which is just a special case of NSBox). I've placed the component into the interface, but what to adjust the thickness of the line.

NSBox has a setBorderWidth method, but doesn't seem to have this exposed when in Interface Builder. I would prefer not to do this manually, as I don't want to have to maintain an object simply to adjust this single value.

Is there a way to set this via Interface Builder that I am just missing?

Or, failing that, is there a better way to put a Horizontal Line in your UI such that you can control it's attributes via Interface Builder?

Answer 1

On the Attributes pane of the inspector, set the Border Type to Custom. Then on the Size pane, set the border width as needed.
